Employer demanding drug & dental plan premiums

Greetings,

Need some guidance.

I have been on LTD since Oct. 2025.

My employer changed their drug & dental plan effective 1/1/2026.

Under the previous plan, I was not required to pay drug plan, extended health care and dental premiums while on disability.

However, under the new plan, the company is demanding that I pay the premiums for drug & dental plan.

They have sent me a letter threatening to terminate my drug & dental benefits.

Can they make this switch while I am on disability and make me pay the premiums?

My LTD benefit is 60% of my previous salary and I would really struggle to pay insurance premiums.

I am trying to work it out with HR but they are not being helpful.

Is this common, and is the employer allowed to do this?

Thanks,

Desmond
