Attitudes to work; qualities and jobs

Work is a wide idea: any activity, paid or unpaid (for example housework). A job is a specific position for which you are paid. A profession needs special education and training (doctor, lawyer). A wage is usually paid by the hour or week, a salary is a fixed amount per month. Perks are extra benefits besides pay (free lunch, a bonus). To describe jobs we use defining clauses: A teacher is a person who teaches. A job which is very demanding needs a lot of energy. We use who for people, which for things and that for both; there is no comma in such sentences. For preferences: I would enjoy working outdoors; I wouldn’t like a job where I have to work at weekends.
