Some 70 MPs wrote to Rowe last week to complain about the pay changes he is making for employees, which will involve cutting premium pay on Sundays and bank holidays, as well as lowering pension contributions.
They asked to meet with Rowe, but in a response seen by City A.M., he said they should talk with Sacha Berendji, M&S' head of retail, and Deborah Warman, head of HR, instead.
M&S staff will be receiving an increase in basic pay, and after a consultation with staff, the business agreed to increase the amount of money it is offering as a one-off payment to those affected.
However, MPs writing to Rowe said the affected staff will have to work for longer hours in 2019 for the same pay they received this year. The group asked the M&S chief: "Mr Rowe, will you also guarantee that you will earn no more in three years' time than you do today?"
Rowe did not agree to freeze his salary for three years in his response letter. He pointed to the company's most recent annual report, in which executive directors turned down a pay rise "in recognition and support of the proposed new pay arrangements being made elsewhere in the UK organisation".
M&S' executive directors also "indicated an intention" to turn down pay increases next July, but have not said whether they would do the same in future.
Documents seen exclusively by City A.M. show how one employee is facing a 20-year pay freeze under the company's changes.
"I cannot help but wonder how Lidl and Aldi manage to make a profit and still pay an hourly rate now higher than the £8.50 that Marks is using as an excuse to erode all the premiums," the employee said.
