A Successful Day

Marianne understands that employment disputes can cause considerable disruption and stress for both the employer and employee.

“If I manage to alleviate these for my clients it has been a successful day. When I receive feedback from my client along these lines, I know I have made a difference.”

Supporting Clients

Marianne tailors her approach to each individual client’s needs, which allows her to support them in the best way.

“I think it is important to know your client, understand what they wish to achieve in any given situation and focus attention on that outcome.

Clients appreciate a speedy and professional, pragmatic response and, more often than not, plain speaking.”

Rewarding Elements

For Marianne, the most rewarding part of her role is knowing that she has made a difference to her client.

A Historical Trial That Marianne Would Have Liked To Have Attended

Marianne would have been fascinated to attend the case of Gill and Coote v El Vino Co Ltd, heard at the Court of Appeal in 1982.

Marianne says:

“Tess Gill (a Solicitor) and Anna Coote (a Journalist) brought a case against El Vino objecting to their policy of refusing to serve women at the bar, instead requiring them to order by table service in a back room, which they asserted breached the Sex Discrimination Act 1975.

They lost the case as it was decided that the women had not suffered any unfavourable treatment, but they appealed this as they rejected El Vino's assertion that the policy was beneficial to women, protecting them from "pushing and jostling" at the bar.

The Court of Appeal agreed with Gill and Coote as it denied women a choice of where to be served and prevented them from mixing with men in the bar where they might pick up information from other journalists and lawyers.

The case is widely considered a landmark decision in the furtherance of women's rights, in particular, where equality is denied on the grounds of perceived courtesy.”

I can't tell you how much I've appreciated your help with this matter, it felt like a complete minefield prior to your input.

You've really helped guide me through what is quite a stressful situation and come out the other side with compensation and a new job too...

Amazing service from Marianne Pieterse who helped me with a settlement agreement.

Marianne was prompt with responding to my initial enquiry with clear, concise information. Once engaged, Marianne's expertise and advice enabled me to negotiate amendments to certain clauses in the contract which were agreed to by my employer.

I thank Marianne for all her help, from initial phone call to sending me the signed agreement.

I would recommend Marianne to anyone seeking employment law advice
