my employer assured me I would receive 16 weeks continuous pay so I signed the letter they gave me. They then paid me in one lump sum payment the following week, costing me much more in income tax than I had anticipated. If they had said it would be paid in a lump sum, I would not have signed, but negotiated the money be put into RSP. This was not what I had agreed to. Could this nul and void the letter of termination?
