Work.

and employer thinks there's no guarantee that she will get ILR.

that's the problem, the employer will be in if she doesn't get ILR but carries on working there. bad timing for the lady.

thou my misses was never asked about ILR when she worked for the NHS after her spouse visa expired

in the job i started 6 months ago, i was even asked for evidence of right to work here, and the director who offered me the job i first meet near 10yrs ago
