What does ETA mean?

Working from home in this situation, has been thrust on employees who haven't fully rearranged their job to because of the post-disaster recovery phase.

Part of my job requires collaborating with internal clients and other business depts....both which won't happen in a fully productive way, when other parts of the organization aren't normal either.

It's different being self-employed vs. working from home regularily (not just one-offs, ie. several times per yr. to focus on report writing, etc.) which within our employer's conditions, would be a signed agreement, arrangements on ergonomics and other stuff agreed between employee and manager.

Part of job is affected also because certain projects are on hold 'cause there maybe other pressing new project work required by senior management. Will know soon.
