The aim of this paper is to analyse the asymptotic properties of the C-metric, using a general method specified in the work of Tafel and co-workers (Tafel and Pukas 2000 Class. Quantum Grav. 17 1559–70, Tafel 2000 Class. Quantum Grav. 17 4397–408, Tafel and Natorf 2004 Class. Quantum Grav. 21 5397–407). By finding an appropriate conformal factor Ω, it allows the investigation of the asymptotic properties of a given asymptotically flat spacetime. The news function and Bondi mass aspect are computed, their general properties are analysed, as well as the small mass, small acceleration, small and large Bondi time limits.

Teleworking is a specific type of work where the employee works outside their usual place of work. A characteristic of this activity is the reduction of the need to commute to their employer's workplace and the performance of work during fixed working hours. The following prerequisites are important for real telework: a computer. The worker is in a different place than the employer or the customer. Communication takes place at a distance via telecommunication networks. Instead of a fixed time regime, teleworking allows the employee to individually optimize the performance of their work according to their own needs in terms of time and place (the workplace is most often home). We use the method of identification, analysis, comparison and synthesis of various legal regulations for teleworking all around the world. In teleworking, the powers of the employer and its employees are not equal. That is why it is necessary to create national laws that will better protect the rights of teleworkers.

Teleworking brings many advantages to employees and employers, but it also brings new demands for both sides. This work arrangement also involves some disadvantages. Most of these disadvantages may be partially eliminated by following the recommended processes. Nevertheless, some negative aspects still need to be expected. Teleworking may have advantages and disadvantages for the entire society, which may not be the same as individual or company interests. This work arrangement has become more and more common also in tourism. It is mainly used by field workers.
